Aster DASKAT Cultivar Uniform Growth and Floret Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Aster novi-belgii cultivars lack uniform plant growth habit and desirable inflorescence form, with limited post-production longevity and variation in floret colors.
Innovation Solution
The development of the new cultivar 'DASKAT' through controlled breeding, which exhibits an upright and inverted conical plant habit, gray-green foliage, freely flowering habit, and a composite inflorescence with 250-300 red-purple ray florets, offering improved compactness and increased ray floret production compared to existing varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing Aster novi-belgii cultivars are used, then they have basic flowering capability, but they lack uniform plant growth habit and desirable inflorescence form
Solution Approach 1:
The patent applies parameter changes by selecting and fixing specific phenotypic parameters during breeding: plant habit (upright and inverted conical), foliage color (gray-green), and inflorescence characteristics (250-300 red-purple ray florets with 10-15 green disc florets). This standardization of parameters achieves uniform growth habit while maintaining desirable aesthetic variations.
2Duration of action of stationary object
If existing Aster cultivars are used, then they have limited post-production longevity, but the new cultivar achieves approximately 27 days of inflorescence color and substance maintenance
Solution Approach 1:
The patent applies preliminary action through controlled breeding programs that pre-select and fix genetic traits for extended post-production longevity before commercial propagation. The cultivar 'DASKAT' was developed through systematic breeding to inherently possess 27-day inflorescence maintenance capability, which is then consistently reproduced through vegetative tip cuttings without requiring post-planting interventions.
3Manufacturing precision
If the new cultivar 'DASKAT' is developed through controlled breeding, then it achieves uniform growth habit and desirable inflorescence form, but this requires a systematic breeding program
Solution Approach 1:
The patent applies self-service by creating a cultivar that inherently possesses and maintains its desirable traits through natural genetic fixation rather than requiring continuous external breeding interventions. Once the uniform growth habit and inflorescence form are established through breeding, the cultivar self-reproduces these characteristics faithfully through vegetative propagation, eliminating the need for complex ongoing breeding programs.

AI summary
A new distinct cultivar of Aster plant named ‘DASKAT’, characterized by its upright and inverted conical plant habit; gray-green foliage; freely flowering habit; decorative, composite-type inflorescence with about 250 to 30 red-purple-colored ray florets; and only about 10 to 15 green-colored disc florets per inflorescence (almost 100% filled capitulae).
